>>Hey Guys, I am having an interesting issue. I have two combos that have the same late bound datasource designed to allow the user to select a subset of the dataset. One Start combo and one stop combo. The code is way simple.

>>The problem is when you select a value in one combo the value of both combos changes to the selected value. This is true when using the mouse or the arrow keys. There are no events registered and I have deleted and recreated the combos with new names. Any combos on the page using the datasource display the same item.

>>My humble thanks in advance,

I was afraid this was the answer. However, it seems like a real bug. I will load down the app with a copy of data that is already loaded.

Thanks.
